separate set of a few of the most necessary 
re-agents in their utmost purity, and if only 
employed when absolutely required, a very 
moderate quantity will suffice. In the sub- 
joined list we have distinguished by the 
word pure those substances which require 
particular pains to be obtained absolutely 
pure. Mixtures of each of the stronger 
acids and water in two or three different 
and known proportions should also be kept. 
N. B. The letter D implies that the dry 
substance should be kept, and S, that it 
should be in solution.
